Requiring 98,590 tons of steel to construct,
the 525 feet tall and 518 feet wide structure held an
interior volume of 129,428,000 cubic feet — about 3.75 times that of the Empire
State Building. It also set various records, including having the largest doors
on earth at 456 feet high, which take nearly 45
minutes to fully open and close.

Nowadays, the monstrous structure is being renovated with
new work platforms for NASA's mission to
explore Mars.
